TIRE.

Specicaton of Letters Patent.

Patented July 2, 190'?.

Application filed April 5,-l906 Renewed May 9, 1907. Serial No. 372,763.

To all whom it may concern:

Be it known that I, ELEAZER KEMrsHALL, a citizen of the United States, residing at Boston, in the county of Suffolk and State of Massachusetts, have` invented certain new and useful Improvements in Tires, of which the following is a specification.

This invention relates to improvements in vehicle tires, such as disclosed in my co-pending application No. 314,273, sled April 2s, 1905.

Inl my present improvement, I provide transversely arranged cup-shaped resilient sectionswith plugs, and relatively non-resilient sections formed with openings to receive the plugs, and adapted to it Within the cupi shape resilient sections; the whole when assembled in tire ormbeing vulcanized to bind the sections together.

' When the sections have thus been assembled and vulcanized, a tire is produced which possesses as its chief characteristic, a resilient core, and embedded non-resilient strengthening sections, lthe flanges of the cup-shape sections forming the outer covering. By such a construction a cheap anddurable structure is the result', the details et cetera, and advantages there-v of being pointed out inthe description and claims.

In the drawings :-Figure l is a side elevation of a portion of a tire and wheel partially in section to disclose the invention. Fig. 2 is a detail sectional view of the tire before being vulcanized to bind the sections together. Fig. 3 is a perspective transverse section of my tire partially broken away, and mounted on a.' telly. Fig. 4 is a detail perspective view of a resilient section.

Fig. 5 is a detail perspective view oi a non-resilient section. Fig. 6 is a detail sectional view of a modification.

` Referring to the drawings 1 indicates a rubber section, provided with a surrounding outwardly extending flange 2, and a projection or plug 3. The flange 2 is slightly thicker on the outer edge to provide a tread 4 tio'n 6, of leather or like material, formed with a pertoration to receiyefthe plugs 3. The non-resilient sections are of such size'idshapgmas todlit nicely within the ange 2, so that when the sections are assembled in tire form, the outer face oi a non-resilient section will be ush with theouter face of the flange of the resilient sectionto squarely abut against the flat face 8 of the adjacent resilient section.

In the manufacture of tires constructed in accordance with my invention, the. non-resilient sections 6, are fitted in the cup-shaped resilient sections and they are thus assembled side by side in tire form, and cetogether.

mented together as shown, clearly inFig. 2. A iter they are so assembled, the whole is subjected to a vulcanizing process to bind the resilient contacting faces That is, the faces of the flanges 2, and the faces 3 o the plugs 3 are fused to the fiat faces of the resilient sections l. By this peculiar construction, separate covering for the sections ist dispensed with, which is a considerable item of expense saved in the cost of manufacture, and at the same time the nonresilient sections oi material, which, of course, are unaffected by the vulcanizing process, are securely embedded in rubber. and are prevented from lateral movement by the plugs. Furthermore, the plugs1 after the vulcanizing process is completed provide a substantial core of resilient material. Obviously more than one core may be used if desired, as it may be preferable when constructing tires for heavy vehicles.

ln Fig. 6, I have shown a slightly different form of my invention, in that the resilient sections la, are

ilanges to partially overlap the adjacent non-resilient flanges 250i two resilient sections to incase the alternate section of non-resilient material, however, thev edect and result is exactly the same as heretofore described.

The invention is extremely simple, and affords a means of constructing a cheap and at the same time durable tire.

What I claim as new and desire to secure by Letters Patent is:-

1. A tire composed of alternate sections of resilient and non-resilient sections of material, iiariges formed on the tcsilient sections to vincase the nonresilent sections, said reslientsections being vulcanized to bind the sections together.

2. A tire composed of alternate sections or' rubber and leather sections, flanges formed on the rubber sections to ipcase the leather' sections, and means for binding the sections 'togetheix 3. A tire composed of alternate sections of resilient and non-resl1ient sections of material, the resilient sections having ilanges which abut against an adjacent resilient section, the resilient sections being lvulcanized and fused together at the points of contact.

4. A tire composed of alternate sections of rubber und leather sections, flanges formed on the rubber sections to incase the leather sections, said rubber sections being vulcanized to bind the sections together.

5. A tire composed of alternate sections of resilient and non-resilient sections of material, a flange formed on each resilient section, said lla-nge inclosing the non-resilient section and abutting against the alternate resilient section and vulcanized thereto. r

6. A tire composed of alternate sections of resilient and non-resilient sections of material, each resilient section of material having a fiat surface and a fiange extending in an opposite direction from the dat surface, said flange incasng the adjacent non-resilient section and abutting against the flat ffice off ik@ materna-ie im" bien@ secinn mi-,aanized thereto.
